That statement is way too absolute to be true.
There is no single “food you eat every week” that is universally “real poison” for the body. Toxicity depends on dose, frequency, and the person, not on dramatic labels. Almost any common food can be harmful in extreme amounts, and almost any “bad” food can be harmless in moderation.
What people usually mean when they say this kind of thing is one of these:
- Ultra-processed foods (chips, sugary drinks, instant noodles) → linked to higher risk of obesity, diabetes, and heart disease when eaten too often.
- Trans fats / deep-fried fast food → genuinely harmful in excess, especially for cholesterol and heart health.
- Very high sugar intake → contributes to insulin resistance and weight gain over time.
- Excess salt → can raise blood pressure.
But calling any one food “poison” is misleading. Even things like salt, sugar, or caffeine are essential or safe in normal amounts.
If you tell me what specific food you’re thinking of, I can break down whether it’s actually harmful, or just unfairly demonized.
